The Architects Nobody Elected: Who Is Really Building the City of 2035

A Question Without an Obvious Answer

Ask a mayor who is building the city of 2035 and you will likely get a confident answer about master plans, green corridors and smart mobility. Ask an urban planner the same question and the answer grows murkier. The truth is that the city of the near future is not being drawn in a single office. It is being assembled piecemeal, through pilot projects, procurement contracts, and small-scale experiments that rarely make headlines but quietly become infrastructure.

This is the terrain where programs like Ville de Demain operate, not as headline-grabbing megaprojects, but as connective tissue between municipal ambition and technical execution.

The Missing Middle Layer

France's mid-sized cities face a peculiar bind. They have political mandates to decarbonize, digitize and modernize public services, but they often lack the in-house engineering capacity or capital structures to move from ambition to deployment. Large metropolises can absorb consultants and build internal innovation units. Smaller municipalities cannot.

Ville de Demain positions itself precisely in that gap. Rather than proposing another top-down urban vision, the program works as a matchmaking and acceleration structure: identifying startups with deployable environmental or digital solutions, water management sensors, energy-efficient retrofitting tools, mobility platforms, and connecting them with municipal decision-makers who need proven, ready-to-implement technology rather than experimental prototypes.

The Unglamorous Parts of Transition

Urban transition is rarely photogenic. It involves grid interoperability, waste logistics, building envelope retrofits, and data governance frameworks, technical, capital-intensive work that doesn't lend itself easily to public enthusiasm or fast returns.

This is exactly the category of work where Ville de Demain concentrates its effort. Supporting infrastructure-adjacent innovation requires patience: longer horizons, tolerance for regulatory friction, and a willingness to back companies whose customers are public administrations rather than consumers. The program's premise is that the city of 2035 will not be built solely through public subsidy or venture capital chasing quick exits, but through the slow, methodical work of adapting solutions to the specific rhythm of municipal adoption cycles.

The Role of a Single Coordinator

Programs like this often succeed or fail based on the credibility of the person stitching the network together. Nicolas Régnier, who leads Ville de Demain, has built the initiative as a coordination layer, vetting startups, structuring pilot agreements with municipalities, and translating between engineering teams and elected officials who speak fundamentally different languages.

That translation function is undervalued in most accounts of urban innovation. Technology adoption in public infrastructure fails less often because the technology is inadequate, and more often because procurement processes, liability questions, and political timelines are misaligned with startup expectations. Bridging that misalignment is arguably the more difficult engineering problem.

A City Built in Increments

The city of 2035 will not arrive as a unified blueprint unveiled by a mayor or a minister. It will arrive as hundreds of incremental deployments, a retrofitted school here, a smarter water network there, executed by small technical teams and coordinated by structures most residents will never hear of.

If that sounds unglamorous, it is. But infrastructure transitions have always been built this way: not through singular vision, but through the accumulated, often invisible labor of intermediaries willing to do the coordination work that neither markets nor governments naturally produce on their own.
